Crafting high-quality Attractive Territorial Spaces(ATS) has become an essential approach to enhancing the quality of national territorial spaces at present. Previous studies have offered multidimensional identification methods but have overlooked the intrinsic connections between ATS and factors such as ecology, culture, and society. This study proposes a systematic method for identifying and optimizing ATS, which includes assessing the supply-demand ratio of ecosystem services(ES), interactive detection of driving factors, identification of ATS, landscape pattern analysis, and a matrix of optimization strategies for ATS. The results indicate: (1) There is a significant spatial imbalance between the supply and demand of ES in Gansu Province, with the western region serving as a crucial water source and carbon sink area, while the eastern region stands out in the provision of cultural services. The supply-demand ratio analysis reveals an imbalance in key services such as water resources and soil conservation(SC), particularly in densely populated and rapidly developing economic regions where the demand is urgent. (2) Geographic detector analysis reveals that Normalized Difference Vegetation Index(NDVI) and population(POP) are the two main driving factors affecting the spatial differences in ES, with NDVI having a high explanatory power for the spatial heterogeneity of carbon sequestration(CS) services, and POP significantly influencing recreation(RE) and aesthetic landscapes(AL) services. (3) Landscape pattern analysis shows that urban spaces exhibit fragmentation; agricultural spaces, though concentrated, lack landscape diversity and connectivity; ecological spaces, despite having larger core areas, have weak connectivity between patches and a high degree of fragmentation. Based on the above analysis, this study has constructed the Attractiveness Territorial Index (ATI), combined with the main functional areas of Gansu Province's territorial space planning, identified ATS, and proposed targeted optimization strategies for territorial spaces. The framework for identifying ATS established in this study effectively implements the requirements of higher-level planning, clarifies guidance and control requirements, and is conducive to enhancing the value and quality of territorial spaces, as well as providing systematic and holistic protection for elements of attractiveness.
